My doctor suggested I keep The Four F's in mind: Fluid, Fiber, Fitness and Fruit . . . I'm not sure what the value of fruit, per se is, but I guess it includes fiber and glucose, which can move intestinal material along smoothly. I have suffered from four terrible diverticular flare-ups in the past five years (not a lot, but enough . . . .), and I can track all four back to not having drunk enough water nor having moved around much. in the end, the best action to take is to drink clear liquids for a day, or sa: coffee, bullion (especially bone broth, which provides a lot of protein), hot tea, more water, more tea) and slowly move back to a normal high-fiber diet. This remedy works every time.
